The purpose of this study was to measure the changes of regional cerebral blood flow(rCBF) and blood pressure(BP) in rats, following the intravenous injection of Flos Sophora japonica L.(FSJ) water extract. The measurement was continually monitored by Laser-Doppler Flowmeter and pressure transducer in anaesthetized adult Sprague-Dawley rats for 2 hours to 2 hours and a half through the data acquisition system. FSJ increased the changes of rCBF in rat significantly. The rCBF of FSJ did not change by pretreated propranolol, atropine, L-NNA($N^G$-nitro-L-argininine) and indomethacin. But the rCBF of Flos Sophora japonica L. was increased by pretreated methylene blue. FSJ decreased the changes of BP, significantly. The BP of FSJ did not change by pretreated propranolol, atropine, L-NNA and indomethacin. But the BP FSJ was decreased by pretreated methylene blue. There results indicated that FSJ can increase the rCBF and decrease the BP, that is related to guanylyl cyclase activity.

The supporting system for agricultural workforce and education strategy has been changing both domestically and worldwide range term. To change the fundamental directions, much more needs to be learned about the process of structural adjustment regarding the dynamics of the agricultural and rural sectors. A rural development doctrine must pay more attention to the ongoing problems of population imbalance and the dissolution of the countryside. The focus should be young people prefer to live in cities because there are more opportunities, services, and great personal fulfillment. This paper was described the effective fostering directions of young agricultural workforce and educational program to prepare future and young farmer for teaching careers in agriculture, food, farm management, and marketing. To achieve these goals, the specific approaches are 1) establish the strong partnership between related organizations of agricultural business, 2) strengthen the management and marketing education of products, 3) create the various in-farming or out-fanning incomes including green tourism, 4) enhance the aggressive marketing strategies by Internet, Telephone, and TV etc, 5) make the association among the same items for the effective research and risk management.

Augmented reality, which has recently drawn great attention, has along history in technical terms. However, the latest emergence of mobile augmented reality using smartphones is allowing people to access augmented reality more easily and faster than ever. However, a review of existing studies shows that most of them have focused on the technical realization of augmented reality, whereas few studies have dealt with how users perceive augmented reality. For users, augmented reality is a means of knowledge transfer, which enables the experience of more abundant reality by providing additional informatio nsources to objects or landscapes. There fore, the element of experience must be considered for the perception of users. In addition, the current augmented reality technology certainly provides users with more fun than any other existing technologies. In this regard, this study intended to divided experiences not only into sensory experiences, but also into entertainment, educational, escapist, and esthetic experiences based on the experience economy theory suggested by Pine and Gilmore(1998). Moreover, this study intended to examine whether mobile augmented reality applications, which are highly popular as a means of the experience economy, influence the usefulness, convenience, and enjoyment perceived by users, and to identify which of these cognitive elements influence usage intentions.

Purpose: This study sought to explore current status of children's swimming pool in Korea and to generate insights regarding safety management of children's swimming pool. Research design, data, and methodology: The study reviewed literatures including documents of Ministry of Culture, Sports and Tourism and sport facility-related articles. Furthermore, the study collected additional statistics via search engines. Results: First, numbers of swimming pools have been dramatically increased since 2016 and Korea experienced an increase of 37% from 2010 to 2019. Of the 611 indoor swimming pools, most swimming pools are located in Gyeonggi province with 27.7% (n=169). Seoul and Gyeonggi-do have the highest proportion of swimming pools in Korea. Second, in types of swimming pools, 47.6%(n=291) was children's swimming pool which is the highest proportion in the nation. Children's swimming pools are also mostly located in Seoul and Gyeonggi province with 57%. Third, of 372 profit swimming pools, children's pools show the highest number with 78%(n=291). Conclusions: Children's swimming pools are picking up faster than the other types of swimming pool. Yet, safety-related studies are still lack. This provides motivations to produce managerial insights from academia and business sectors. Moreover, more studies of legal issues should be conducted. Implications were discussed.

Recent economic and income growth in Korea has caused people to seek healthier and happier lives. Forests are seen as spaces that provide tourism and recreation. The Korea forest service and local governments are developing and designating recreational forests but previous studies on the subject have only covered customer satisfaction and how forests are used. As such, the current study aims to find issues with designation criteria for recreational forests used by Gwangju city in Gyeonggi province and suggest improvements to the system. Site E was deemed the most adequate in evaluations of five candidate site. The criteria used in the evaluations were problematic due to (1) a lack of differentiating power in evaluation items, (2) blanket coverage of score ranges, (3) a lack of additional points for special sites, and (4) unclear evaluation indices. Based on the identified issues, the current study suggests introducing additional points and clearly detailing evaluation indices and items to enhance the evaluation of recreational forest candidate sites.

Forest fires have potentials to change the structure and function of forest ecosystems and significantly influence on atmosphere and biogeochemical cycles. Forest fire also affects the quality of public benefits such as carbon sequestration, soil fertility, grazing value, biodiversity, or tourism. The prediction of fire occurrence and its spread is critical to the forest managers for allocating resources and developing the forest fire danger rating system. Most of fires were human-caused fires in Korea, but meteorological factors are also big contributors to fire behaviors and its spread. Thus, meteorological factors as well as social factors were considered in the fire danger rating systems. A total of 298 forest fires occurred during the fall season from 2002 to 2006 in South Korea were considered for developing a logistic model of forest fire occurrence. The results of statistical analysis show that only effective humidity and temperature significantly affected the logistic models (p<0.05). The results of ROC curve analysis showed that the probability of randomly selected fires ranges from 0.739 to 0.876, which represent a relatively high accuracy of the developed model. These findings would be necessary for the policy makers in South Korea for the prevention of forest fires.

Community search aims at finding a meaningful community that contains the query node and also maximizes (minimizes) a goodness metric. This problem has recently drawn intense research interest. However, most metric-based algorithms tend to include irrelevant subgraphs in the identified community. Apart from the user-defined metric algorithm, how can we search the natural community that the query node belongs to? In this paper, we propose a novel community search algorithm based on the concept of the k-hop and local distance dynamics model, which can naturally capture a community that contains the query node. The basic idea is to envision the nodes that k-hop away from the query node as an adaptive local dynamical system, where each node only interacts with its local topological structure. Relying on a proposed local distance dynamics model, the distances among nodes change over time, where the nodes sharing the same community with the query node tend to gradually move together, while other nodes stay far away from each other. Such interplay eventually leads to a steady distribution of distances, and a meaningful community is naturally found. Extensive experiments show that our community search algorithm has good performance relative to several state-of-the-art algorithms.
